This is a rare trilobite offering from Malvern, England. It's a very nicely prepared, 1.75" long, Encrinurus. It's Silurian in age, Wenlock Stage. These trilobites are found in hard nodules and require a lot of preparation time. The details on this specimen really show off the skill of the preparitor. The long eye stalk and spines have all been prepared free standing. Only a small handful of these trilobites have ever been collected and nicely prepared like this one.
